The HVAC Smart Chip PLUS™ microprocessor

Tired of Your ELECTRIC BILLS GOING UP EVERY YEAR?

According to Department of Energy 40% to 45% of total energy costs come from HVAC Systems.

The HVAC Smart Chip study commissioned by the California Energy Commission (CEC), conducted by Pacific Gas and Electric, showed that simple changes to the way your HVAC fan works can increase the energy efficiency in your heating and air conditioning system up to 29% with an average just under 15%

By extending the fan cycle for a longer period of time after the heating and cooling cycle is complete, latent heating and cooling is captured that would have otherwise dissipated. Most manufactures of HVAC systems have no fan delay or one of an additional ninety (90) seconds, but CEC studies have revealed that a longer fan cycle yields better energy efficiency.

The HVAC SMART Chip PLUS uses intelligence to ensure optimum performance is delivered every cycle.

Built with 2X’s the Intelligence.

The HVAC Smart Chip PLUS is a simple retro fit and has dual microprocessors that operate in both heating and cooling modes. The first microprocessor monitors system cycle time and adjusts the HVAC fan to stay on for an extended amount of time after the cooling or heating unit cycles off. Most systems are designed for the fan to turn off after 60-90 seconds. It RECORDS how long the cooling or heating unit has been running and AUTOMATICALLY PROGRAMS the fan to remain on for a precise amount of extended time, thus utilizing additional hot or cold air left in the system that would have been wasted and subsequently reduces the number of times the HVAC systems cycles on/off.

The second microprocessor is built with COMPRESSOR SAVING TECHNOLOCGY- for all systems cycling 30 minutes or greater, the compressor will automatically get a 5 minute reprieve, allowing for maximum benefit without any additional wear and tear on the compressor, producing additional electric bill savings.

The end result is better system efficiency, no wasted energy; reducing utility cost all while maintaining the comfort of your home.

Saving Energy in Cooling Mode.

The HVAC Smart Chip Plus monitors how long the AC unit runs, and then automatically programs the fan to continue running until all of the cold air left in the ducts has been delivered to the rooms. The HVAC Smart Chip PLUS will allow the fan to run no more than 2 minutes additionally for every 10 minutes of run time to cool the conditioned space at the same time preventing the water from evaporating across the coil and getting the moisture back into the home. While some AC manufacturers program the fan to run for 90 seconds after the AC compressor turns off, recent testing by the California Energy Commission shows an average 15-20%% improvement in efficiency with extended run time. The extended fan time reduces the number of times the AC compressor cycles on—one of the worst energy guzzlers in both commercial and residential buildings. If an HVAC unit includes a high efficiency fan motor, the savings will be higher due to lower power consumption of the fan motor.

Saving Energy in Heating Mode.

Most furnace systems operate with a low speed fan in heating mode. After the furnace turns off the fan continues to operate for a fixed time delay of 90 seconds or the fan continues to operate based on a temperature delay which turns off the fan when the plenum temperature falls below a control threshold of 100 to 200°F depending on whether or not the temperature delay sensor is operating or set properly. The HVAC Smart Chip provides high speed fan operation in heating mode to increase heating efficiency and reduce furnace run time. The HVAC Smart Chip monitors how long the furnace runs, and then activates the furnace fan at the end of the combustion cycle to stay on for up to 8 minutes longer. The additional fan run time extracts more heat from the furnace, resulting in less waste and less run furnace time, saving an average of 15.8% in energy costs.


The HVAC Smart Chip comes with a five (5) year unconditional replacement warranty. If for any reason the HVAC Smart Chip fails to perform within five years of purchase date we will replace for free.
